| Abstract: | The sample is molten by sodium superoxide,leached by water and acidified by hydrochloric acid.In hydrcholoric acid sulphuric acid medium with air isolated,the tetravalent titanium of the sample is reduced to trivalent one by aluminium and then titrated using standard ammonium ferric sulfate solution,with thiocyanate as indicator. |
